CROSS-REFERENCE TO RELATED APPLICATION

The present application is the U.S. national phase application of PCT Application No. PCT/CN2016/109081 filed on Dec. 8, 2016, the disclosure of which is incorporated herein in its entirety by reference.

TECHNICAL FIELD

Embodiments of the disclosure relate to the field of communications, and more particularly to a method and device for wireless communication.

BACKGROUND

At present, there is a multi-beam system that a network device provides multiple beams and thus may provide different coverage through different beams.

In the related art, transmission resources (for example, frequency-domain resources or time-domain resources) available for different beams are fixed. That is, a communication system may specify a transmission resource available for a certain beam and, moreover, during operation of the communication system, the beam may only use the transmission resource specified by the communication system.

With development of communication technologies, communication services also have made increasingly diversified requirements on transmission resources. The same service may have different requirements on transmission resources during different time periods. Since a transmission resource available for a beam cannot be changed, there may exist the condition that the existing multi-beam system cannot meet a service requirement of a terminal device, which seriously affects practicability and user experience of the multi-beam system.

For example, a component may be, but not limited to, a process running on a processor, the processor, an object, an executable file, an execution thread, a program and/or a computer. The drawings illustrate that an application running on computing equipment and the computing equipment may both be components. One or more components may reside in a process or an execution thread, and the components may be located on a computer and/or distributed between two or more computers. In addition, these components may be executed from various computer-readable media with various data structures stored thereon. The “components” may communicate through local or remote processes according to, for example, signals having one or more data packets (for example, data from one component interacting with another component in a local system, distributed system, and/or across a network such as the Internet with other systems by way of the signal).

It is to be understood that the technical solutions of the embodiments of the disclosure may be applied to various communication systems, for example, a Global System of Mobile Communication (GSM), a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), a Long Term Evolution (LTE) system, an Advanced LTE (LTE-A) system, a Universal Mobile Telecommunication System (UMTS) and a next-generation communication system.

For example, the computer-readable medium may include, but not limited to: a magnetic storage device (for example, a hard disk, a floppy disk or a magnetic tape), an optical disk (for example, a Compact Disk (CD) and a Digital Versatile Disk (DVD)), a smart card and a flash memory (for example, an Erasable Programmable Read-Only Memory (EPROM), a card, a stick or a key driver). In addition, various storage media described in the disclosure may represent one or more devices and/or other machine-readable media configured to store information. Term “machine-readable medium” may include, but not limited to, a wireless channel and various other media capable of storing, including and/or carrying instructions and/or data.

FIG. 1 is a schematic diagram of a wireless communication system to which the embodiments of the disclosure are applied. As illustrated in FIG. 1, the communication system 100 includes a network device 102, and the network device 102 may include one antenna or multiple antennae, for example, antennae 104, 106, 108, 110, 112 and 114. In addition, the network device 102 may additionally include a sender chain and a receiver chain. Those of ordinary skill in the art may understand that each of the sender chain and the receiver chain may include multiple components (for example, a processor, a modulator, a multiplexer, a demodulator, a demultiplexer or an antenna) related to signal sending and receiving.

The network device 102 may communicate with multiple terminal devices (for example, a terminal device 116 and a terminal device 122). However, it can be understood that the network device 102 may communicate with any number of terminal devices like the terminal device 116 or 122. The terminal devices 116 and 122 may be, for example, cell phones, intelligent phones, portable computers, handheld communication devices, handheld computing devices, satellite radio devices, global positioning systems, PDAs and/or any other suitable device configured for communication in the wireless communication system 100.

As illustrated in FIG. 1, the terminal device 116 communicates with the antennae 112 and 114, and the antennae 112 and 114 send information to the terminal device 116 through a forward link 118 (also called a downlink) and receive information from the terminal device 116 through a reverse link 120 (also called an uplink). In addition, the terminal device 122 communicates with the antennae 104 and 106, and the antennae 104 and 106 send information to the terminal device 122 through a forward link 124 and receive information from the terminal device 122 through a reverse link 126.

For example, in a Frequency Division Duplex (FDD) system, for example, the forward link 118 and the reverse link 120 may use different frequency bands, and the forward link 124 and the reverse link 126 may use different frequency bands.

For another example, in a Time Division Duplex (TDD) system and a full duplex system, the forward link 118 and the reverse link 120 may use the same frequency band, and the forward link 124 and the reverse link 126 may use the same frequency band.

Each antenna (or an antenna group formed by multiple antennae) and/or region designed for communication are/is called sectors/a sector of the network device 102. For example, the antenna group may be designed to communicate with terminal devices in a sector of a coverage area of the network device 102. The network device may send signals to all the terminal devices in the corresponding sector through a single antenna. In a process that the network device 102 communicates with the terminal devices 116 and 122 through the forward links 118 and 124 respectively, a sending antenna of the network device 102 may also use beamforming to improve signal-to-noise ratios of the forward links 118 and 124. In addition, compared with a manner that the network device sends signals to all the terminal devices in the corresponding sector through the single antenna, when the network device 102 sends signals to the terminal devices 116 and 122 randomly scattered in the related coverage area by use of beamforming, a mobile device in a neighbor cell may be interfered less.

In a given time, the network device 102, the terminal device 116 or the terminal device 122 may be a wireless communication sending device and/or a wireless communication receiving device. When data is sent, the wireless communication sending device may code the data for transmission. Specifically, the wireless communication sending device may acquire (for example, generation, receiving from another communication device or storing in a memory) a certain number of data bits to be sent to the wireless communication receiving device through a channel. The data bits may be included in a transmission block (or multiple transmission blocks) of the data, and the transmission block may be segmented to generate multiple code blocks.

In addition, the communication system 100 may be a PLMN network, a D2D network, an M2M network or another network. FIG. 1 is only a simplified schematic diagram listed as an example, and the network may further include another network device which is not presented in FIG. 1.

In the embodiments of the disclosure, the network device may form multiple beams through one or more antennae, for example, by regulating direction angles (angles in a horizontal direction) and downtilt angles (angles in a vertical direction) of the antennae, here, each of the multiple beams has coverage. For example, as illustrated in FIG. 2, it is assumed that coverage of a beam (recorded hereinafter as beam #α for convenient understanding and distinguishing) of multiple beams used by the network device is a range #α and, moreover, it is assumed that coverage of another beam (recorded hereinafter as beam #β for convenient understanding and distinguishing) of the multiple beams used by the network device is a range #β. Then, in the embodiments of the disclosure, for example, the range #α and the range #β may be different, or, coverage of the range #α is not overlapped with coverage of the range #β.

For another example, the range #α and the range #β may be partially identical, or, the range #α is partially overlapped with the range #β.

For another example, the range #α and the range #β may be completely identical, or, the range #α is completely overlapped with the range #β.

Moreover, in the embodiments of the disclosure, the size of the range #α may be larger than the size of the range #β; or, the size of the range #α may also be smaller than the size of the range #β; or, the size of the range #α may also equal to the size of the range #β. There are no special limits made in the disclosure.

In the embodiments of the disclosure, the terminal device may use one beam for communication and may also use multiple beams for communication. There are no special limits made in the disclosure. In the embodiments of the disclosure, a beam group may include each beam used by the same terminal device (for example, during the same time period).

Moreover, in the embodiments of the disclosure, transmission resources available for one or more beams of the multiple beams used by the network device may be the same, or the transmission resources available for any two beams of the multiple beams used by the network device may be different. There are no special limits made in the disclosure. Under this condition, in the embodiments of the disclosure, a beam group may include each beam for which the same transmission resource is available (for example, during the same time period).

In the embodiments of the disclosure, the terminal device, before using a certain beam group (specifically, one or more beams in the beam group) for service transmission, is required to learn a transmission resource available for the beam group.

In the embodiments of the disclosure, “the transmission resource available for the beam group” may refer to that the transmission resource is allocated for the beam group and the beam group may select to use all resources of the transmission resource and may also select to use part resources of the transmission resource.

Moreover, in the embodiments of the disclosure, each terminal device may learn, through a similar process, a transmission resource available for a beam group where a used beam is located. For convenient understanding and description, descriptions will be made below with a process through which a terminal device #A (i.e., an example of a first terminal device) learns transmission resources available for a beam group #1˜beam group #M where a used beam #1˜a used beam #N are located as an example.

Herein, N≥1 and M≥1. In the embodiments of the disclosure, multiple beams (two or more than two) of the beam #1˜the beam #N may belong to the same beam group (namely N<M), or, any two beams of the beam #1˜the beam #N belong to different beam groups (namely N=M).

FIG. 3 illustrates an interaction process through which the network device and the terminal device #A determine M beam groups (the beam group #1˜the beam group #M).

As illustrated in FIG. 3, in S210, the network device may determine a transmission resource available for each of the M beam groups.

Herein, a similar method and process is adopted to determine the transmission resource for each beam group. For convenient understanding and description, descriptions will be made below with a method and process for determining the transmission resource for the beam group #1 as an example.

At first, an opportunity for determination and transmission of the transmission resource for the beam group #1 by the network device will be described.

For example, in the embodiments of the disclosure, the network device may periodically determine and transmit the transmission resource for the beam group #1. That is, in the embodiments of the disclosure, a time-domain resource used by the communication system may be divided into multiple periods. The network device may determine and transmit the transmission resource for the beam group #1 at a certain moment in each period (for example, a starting moment of the period).

For another example, in the embodiments of the disclosure, the network device may be triggered to determine and transmit the transmission resource for the beam group #1. That is, in the embodiments of the disclosure, the network device may determine and transmit the transmission resource for the beam group #1 responsive to it is determined that a condition related to the beam group #1 is met.

Exemplarily but unlimitedly, in the embodiments of the disclosure, the condition related to the beam group #1 may be determined according to a requirement related to a service carried on one or more beams in the beam group #1.

Therefore, after the requirement related to the service carried on the one or more beams in the beam group #1 changes (for example, a change in the requirement related to the service carried on the one or more beams in the beam group #1 is greater or equal to a specified change range), the network device may determine that the transmission resource for the beam group #1 is required to be re-determined and retransmitted.

Moreover, exemplarily but unlimitedly, in the embodiments of the disclosure, the requirement related to the service carried on the one or more beams in the beam group #1 may be determined on the basis of information related to the one or more beams in the beam group #1.

Herein, the information related to the one or more beams in the beam group #1 may include one or more of the following parameters.

A parameter #1: the number of terminal devices within coverage of the one or more beams in the beam group #1.

For example, if the number of the terminal devices within the coverage of the one or more beams in the beam group #1 increases, the network device may determine that the transmission resource for the beam group #1 is required to be redetermined and retransmitted.

Specifically, if the number of the terminal devices within the coverage of the one or more beams in the beam group #1 increases to exceed a specified number threshold #A, the network device may determine that the transmission resource for the beam group #1 is required to be re-determined and retransmitted.

Or, if a value Δ#A by which the number of the terminal devices within the coverage of the one or more beams in the beam group #1 increases is greater or equal to a specified number threshold #B, the network device may determine that the transmission resource for the beam group #1 is required to be re-determined and retransmitted.

For another example, if the number of the terminal devices within the coverage of the one or more beams in the beam group #1 decreases, the network device may determine that the transmission resource for the beam group #1 is required to be re-determined and retransmitted.

Specifically, if the number of the terminal devices within the coverage of the one or more beams in the beam group #1 decreases to be less than a specified number threshold #C, the network device may determine that the transmission resource for the beam group #1 is required to be re-determined and retransmitted.

Or, if a value Δ #B by which the number of the terminal devices within the coverage of the one or more beams in the beam group #1 decreases is greater or equal to a specified number threshold #D, the network device may determine that the transmission resource for the beam group #1 is required to be re-determined and retransmitted.

A parameter #2: a volume of a service transmitted through the beam in the beam group #1.

For example, if the volume of the service transmitted through the beam in the beam group #1 increases, the network device may determine that the transmission resource for the beam group #1 is required to be re-determined and retransmitted.

Specifically, if the volume of the service transmitted through the beam in the beam group #1 increases to exceed a specified number threshold #E, the network device may determine that the transmission resource for the beam group #1 is required to be re-determined and retransmitted.

Or, if a value Δ #C by which the volume of the service transmitted through the beam in the beam group #1 increases is greater or equal to a specified number threshold #F, the network device may determine that the transmission resource for the beam group #1 is required to be re-determined and retransmitted.

For another example, if the volume of the service transmitted through the beam in the beam group #1 decreases, the network device may determine that the transmission resource for the beam group #1 is required to be re-determined and retransmitted.

Specifically, if the volume of the service transmitted through the beam in the beam group #1 decreases to be less than a specified number threshold #G, the network device may determine that the transmission resource for the beam group #1 is required to be re-determined and retransmitted.

Or, if a value Δ #D by which the volume of the service transmitted through the beam in the beam group #1 decreases is greater or equal to a specified number threshold #H, the network device may determine that the transmission resource for the beam group #1 is required to be re-determined and retransmitted.

A parameter #3: a service type of the service transmitted through the beam in the beam group #1.

For example, if the service type of the service transmitted through the one or more beams in the beam group #1 changes, the network device may determine that the transmission resource for the beam group #1 is required to be re-determined and retransmitted.

It is to be understood that the parameters, listed above, configured for the network device to determine whether the transmission resource available for a certain beam group is required to be re-determined are only exemplarily described and not intended to limit the disclosure and other parameters capable of enabling the network device to determine whether the transmission resource available for the beam group is required to be re-determined all fall within the scope of protection of the disclosure.

A method by which the network device determines the transmission resource for the beam group #1 will be described below in detail.

Exemplarily but unlimitedly, in the embodiments of the disclosure, the network device may determine, according to the information related to the one or more beams in the beam group #1, the transmission resource for the beam group #1, for example, a size of the transmission resource, or a position of the transmission resource in a communication resource provided by the system.

For example, the network device may determine whether to increase or decrease the transmission resource for the beam group #1 according to the information related to the one or more beams in the beam group #1.

Exemplarily but unlimitedly, in the embodiments of the disclosure, the above parameter #1˜parameter #3 may be listed as the information related to the one or more beams in the beam group #1.

Specifically, when the information related to the one or more beams in the beam group #1 is the number #α of the terminal devices within the coverage of the one or more beams in the beam group #1 (i.e., the parameter #1), the network device may estimate, according to the number #α, a size of a transmission resource (for example, time-domain resource or frequency-domain resource) meeting service access requirements of all the terminal devices within the coverage of the one or more beams in the beam group #1 and determine the size of the transmission resource for the beam group #1 according to the estimated size of the transmission resource. For example, the network device may make the size of the transmission resource for the beam group #1 approximate to the estimated size of the transmission resource. Specifically, the network device may make a difference between the size of the transmission resource for the beam group #1 and the estimated size of the transmission resource less than or equal to a preset difference threshold.

When the information related to the one or more beams in the beam group #1 is the volume #β of the service transmitted through the one or more beams in the beam group #1 (i.e., the parameter #2), the network device may estimate, according to the volume #β, a size of a transmission resource (for example, time-domain resource or frequency-domain resource) meeting a requirement of the volume #β of the service transmitted through the one or more beams in the beam group #1 and determine the size of the transmission resource for the beam group #1 according to the estimated size of the transmission resource. For example, the network device may make the size of the transmission resource for the beam group #1 approximate to the estimated size of the transmission resource. Specifically, the network device may make a difference between the size of the transmission resource for the beam group #1 and the estimated size of the transmission resource less than or equal to the preset difference threshold.

When the information related to the one or more beams in the beam group #1 is the service type #γ of the service transmitted through the one or more beams in the beam group #1 (i.e., the parameter #3), the network device may estimate, according to the service type #γ, a size of a transmission resource (for example, time-domain resource or frequency-domain resource) meeting a requirement of the service type #γ of the service transmitted through the one or more beams in the beam group #1 and determine the size of the transmission resource for the beam group #1 according to the estimated size of the transmission resource. For example, the network device may make the size of the transmission resource for the beam group #1 approximate to the estimated size of the transmission resource. Specifically, the network device may make a difference between the size of the transmission resource for the beam group #1 and the estimated size of the transmission resource less than or equal to the preset difference threshold.

It is to be understood that the parameters, listed above, configured for the network device to determine the transmission resource available for a certain beam group are only exemplarily described and not intended to limit the disclosure and other parameters capable of enabling the network device to determine the transmission resource available for the beam group all fall within the scope of protection of the disclosure.

Moreover, using manners, listed above, for the parameters configured for the network device to determine the transmission resource available for a certain beam group are only exemplarily described and not intended to limit the disclosure and other manners capable of enabling the network device to determine the transmission resource available for the beam group on the basis of the parameters all fall within the scope of protection of the disclosure. For example, the network device may also determine a requirement of the service carried on the beam group #1 on channel quality on the basis of the one or more parameters, and determine the transmission resource for the beam group #1 (for example, a position of a frequency-domain resource in the transmission resource or a position of a time-domain resource in the transmission resource) according to the requirement on the channel quality.

As described above, in S210, the network device may determine the transmission resource for the beam group #1 used by the terminal device #A. The transmission resource is recorded hereinafter as a transmission resource #A for convenient understanding and description.

In S220, the network device sends to the terminal device #A configuration information that is used to indicate the transmission resource #A, which is determined by the network device above, for the beam group #1.

Exemplarily but unlimitedly, in the embodiments of the disclosure, the configuration information may be used to indicate a configuration of the transmission resource #A.

For example, in the embodiments of the disclosure, the transmission resource #A may include a frequency-domain resource #A-1.

Under this condition, the configuration information may be used to indicate at least one of: a size of the frequency-domain resource #A-1, or a position of the frequency-domain resource #A-1 in a frequency-domain resource provided by the communication system.

Exemplarily but unlimitedly, in the embodiments of the disclosure, the frequency-domain resource provided by the communication system may be divided into multiple frequency-domain units in a frequency domain and, moreover, for example, a subcarrier may be listed as the frequency-domain unit. Therefore, the configuration information may be an identifier used to indicate whether each frequency-domain unit (for example, subcarrier) belongs to the frequency-domain resource #A-1, for example, bit mapping (Bit Map) in the frequency domain.

For another example, in the embodiments of the disclosure, the transmission resource #A may include a time-domain resource #A-2.

Under this condition, the configuration information may be used to indicate at least one of: a size of the time-domain resource #A-2, or a position of the time-domain resource #A-2 in a time-domain resource provided by the communication system.

Exemplarily but unlimitedly, in the embodiments of the disclosure, the time-domain resource provided by the communication system may be divided into multiple time units in a time domain and, moreover, for example, a symbol, a slot, a Transmission Time Interval (TTI) or a subframe may be listed as the time unit. Therefore, the configuration information may be an identifier used to indicate whether each time unit belongs to the time-domain resource #A-2, for example, bit mapping in the time domain.

In the embodiments of the disclosure, the M beam groups may further include another beam group, in addition to the beam group #1. Under this condition, the configuration information may further be used to indicate a mapping relationship (recorded hereinafter as mapping relationship #0 for convenient understanding and distinguishing) between the beam group #1 and the transmission resource #A. Therefore, the terminal device may determine that the transmission resource #A is the transmission resource available for the beam group #1 on the basis of the mapping relationship #0.

In the embodiments of the disclosure, the network device may send the configuration information to multiple terminal devices including the terminal device #A through a PBCH or system information in a broadcast manner.

Or, in the embodiments of the disclosure, the network device may also send the configuration information to the terminal device #A through dedicated signaling, for example, RRC, for the terminal device #A.

In the embodiments of the disclosure, the configuration information may be transmitted in one time. That is, the configuration information may be used to indicate the configuration of the transmission resource #A and the mapping relationship (i.e., the mapping relationship #0) between the beam group #1 and the transmission resource #A.

Or, in the embodiments of the disclosure, the configuration information may also be transmitted in many times (at least twice) in different time periods. This condition will be described below in detail.

A First Manner

In the embodiments of the disclosure, for example, before the terminal device communicates on the basis of a beam and for example, responsive to access of the terminal device to the network device, the network device may send configuration information #A (i.e., an example of first configuration information) to the terminal device. The configuration information #A may be used to indicate configurations of multiple transmission resources including the transmission resource #A.

Therefore, the terminal device may team, according to the configuration information #A, the configurations of the multiple (for example, Q, Q≥M) transmission resources including the transmission resource #A, for example, at least one of a size or position of each transmission resource in the time domain, at least one of a size or position of each transmission resource in the frequency domain, or at least one of a size or position of each transmission resource in the time domain and the frequency domain.

In the embodiments of the disclosure, there may be one or more pieces of configuration information #A and there are no special limits made in the disclosure. In addition, when there are multiple pieces of configuration information #A, each piece of configuration information #A may be used to indicate configurations of one or more transmission resources. Moreover, the multiple pieces of configuration information #A may be sent at the same time and may also be sent at different time and there are no special limits made in the disclosure.

After the network device determines that the beam group #1 is required to use the transmission resource #A, the network device may send to the terminal device configuration information #B (i.e., an example of second configuration information) used to indicate the transmission resource #A. Therefore, the terminal device may determine that the transmission resource #A is the transmission resource available for the beam group #1 on the basis of the configuration information #B and determine the configuration of the transmission resource #A on the basis of the configuration information #A.

In the embodiments of the disclosure, the Q transmission resources may correspond to Q resource identifiers (IDs) (i.e., an example of first IDs) one to one.

Specifically, in the embodiments of the disclosure, when the M beam groups further includes the other beam group, in addition to the beam group #1, the configuration information #B may further be used to indicate the mapping relationship between the transmission resource #A and the beam group #1.

Exemplarily but unlimitedly, in the embodiments of the disclosure, the configuration information #A may further be used to indicate the resource ID (i.e., an example of the first ID) of each of the multiple transmission resources, namely an ID of a transmission resource may be used to uniquely indicate the transmission resource. That is, exemplarily but unlimitedly, the configuration information #A may include the following information.

[resource_set_1, resource_set_2, . . . , resource_set_K], where resource_set_k is the ID of a transmission resource #k (k=1, 2, . . . , K) and K is the number of the multiple transmission resources.

Under this condition, the configuration information #B may include an ID of the transmission resource #A, or, the configuration information may further include a mapping relationship between the ID of the transmission resource #A and an ID of the beam group #1.

Exemplarily but unlimitedly, the configuration information #B may be the resource ID corresponding to the transmission resource #A in [resource_set_1, resource_set_2, . . . , resource_set_K].

A transmission manner for the configuration information #A and the configuration information #B will be described below in detail.

For example, in the embodiments of the disclosure, the network device may send the configuration information #A to the terminal device #A through RRC signaling for the terminal device #A.

Moreover, the network device may send the configuration information #B to the terminal device #A through a MAC CE for the terminal device #A.

Or, the network device may send the configuration information #B to the terminal device #A through DCI for the terminal device #A.

For another example, in the embodiments of the disclosure, the network device may send the configuration information #A to the terminal device #A through a MAC CE for the terminal device #A.

Moreover, the network device may send the configuration information #B to the terminal device #A through DCI for the terminal device #A.

A Second Manner

In the embodiments of the disclosure, for example, before the terminal device communicates on the basis of the beam, and for example, responsive to access of the terminal device to the network device, the network device may send configuration information #C (i.e., an example of third configuration information) to the terminal device. The configuration information #C may be used to indicate a configuration of a transmission resource (for example, a size and position of the transmission resource) in each of multiple (i.e., H, H≥M) transmission resource sets, and mapping relationships between multiple beam groups and the multiple transmission resource sets. Moreover, the transmission resource in each transmission resource set may have an index used to uniquely indicate the transmission resource in the transmission resource set. Each transmission resource set may include at least one transmission resource, the multiple beam groups include the beam group #1 and the transmission resource #A belongs to at least one transmission resource set of the multiple transmission resource sets.

Therefore, the terminal device may team, according to the configuration information #C, the configurations of the multiple transmission resources including the transmission resource #A, for example, at least one of the size or position of each transmission resource in the time domain, at least one of the size or position of each transmission resource on the frequency domain, or at least one of the size or position of each transmission resource in the time domain and the frequency domain.

In the embodiments of the disclosure, there may be one or more pieces of configuration information #C and there are no special limits made in the disclosure. In addition, when there are multiple pieces of configuration information #C, each piece of configuration information #C may be used to indicate configurations of one or more transmission resources. Moreover, the multiple pieces of configuration information #C may be sent at the same time and may also be sent at different time and there are no special limits made in the disclosure.

Exemplarily but unlimitedly, the configuration information #C may include the following information.

[Beam group_i, resource_set_i_1, resource_set_i_2, . . . , resource_set_i_w], where resource_set_w is an ID of a transmission resource #w (w=1, 2, . . . , W), W is the number of transmission resources in the transmission resource set corresponding to Beam group_1, Beam group_i is an ID of a beam group #i and i ∈ [1, M].

After the network device determines that the beam group #1 is required to use the transmission resource #A, the network device may send to the terminal device configuration information #D used to indicate the transmission resource #A. Therefore, the terminal device may determine that the transmission resource #A is the transmission resource available for the beam group #1 on the basis of the configuration information #D and determine the configuration of the transmission resource #A on the basis of the configuration information #C.

Under this condition, the configuration information #D may include the ID of the beam group #1 and an index of the transmission resource #A in the transmission resource set corresponding to the beam group #1.

A transmission manner for the configuration information #C and the configuration information #D will be described below in detail.

For example, in the embodiments of the disclosure, the network device may send the configuration information #C to the terminal device #A through RRC signaling for the terminal device #A.

Moreover, the network device may send the configuration information #D to the terminal device #A through a MAC CE for the terminal device #A.

Or, the network device may send the configuration information #D to the terminal device #A through DCI for the terminal device #A.

For another example, in the embodiments of the disclosure, the network device may send the configuration information #C to the terminal device #A through a MAC CE for the terminal device #A.

Moreover, the network device may send the configuration information #D to the terminal device #A through DCI for the terminal device #A.

In addition, in the embodiments of the disclosure, a transmission resource provided by the communication system includes a transmission resource reserved for a specified channel (for example, a communication channel or a broadcast channel) or a specified service. Moreover, in the communication system, the transmission resource reserved is protected and unavailable for another channel or service. Under this condition, in the embodiments of the disclosure, the transmission resource #A may include no the transmission resource reserved.

Moreover, in the embodiments of the disclosure, the beam group #1 may include multiple beams and the multiple beams may share the transmission resource #A. Therefore, the terminal device #A may perform joint transmission on the multiple beams in the beam group #1.

Or, in the embodiments of the disclosure, the transmission resource #A available for the beam group #1 may be overlapped with (for example, partially identical) a transmission resource available for another beam group, or, the transmission resource #A available for the beam group #1 may be different from the transmission resource available for another beam group. There are no special limits made in the disclosure.

In the embodiments of the disclosure, the transmission resource #A may include a transmission resource (i.e., an example of a first transmission resource) used to carry a control channel.

Moreover, in the embodiments of the disclosure, the transmission resource #A may further include a transmission resource (i.e., an example of a second transmission resource) used to carry a data channel.

Herein, part resources of the transmission resource (i.e., the first transmission resource) carrying the control channel may also be used to carry the data channel.

Moreover, part resources of the transmission resource (i.e., the second transmission resource) carrying the data channel may also be used to carry the control channel.

Herein, the transmission resource (i.e., the first transmission resource) carrying the control channel and transmission resource (i.e., the second transmission resource) carrying the data channel in the transmission resource #A may be the same and may also be different. There are no special limits made in the disclosure.

In the embodiments of the disclosure, beams configured for the control channel and the data channel may be different. For example, transmission resources on two beams are configured for the control channel and a transmission resource on one beam is configured for the data channel.

Moreover, transmission resources for a beam (i.e., an example of a first beam) in the beam group #1 and another beam (i.e., an example of a second beam) in the beam group #1 may be the same and may also be different. There are no special limits made in the disclosure.

If the available transmission resource presently acquired by the terminal device through the DCI and corresponding to multiple-subframe or multiple-slot or multiple-mini-slot/multiple-subslot scheduling is inconsistent with the existing configuration, the terminal device may determine the transmission resource for the beam on the basis of an indication of present latest DCI.

Specifically, in the embodiments of the disclosure, the transmission resource #A may be a transmission resource available for the beam group #1 during a time period #A (i.e., an example of a first time period).

Before a time period #B (i.e., an example of a second time period), the network device may re-determine and retransmit a transmission resource #B available for the beam group #1 during the time period #B.
